Answer:

5 cookies left

Step-by-step explanation:

First you make the fraction equal by multiplying them

2/3 multiply both numerator and denominator by 4

= 8/12

Now you divide 60 by 12 to find the amount to make the denominator 60

60 divided by 12 = 5

8/12 multiply both numerator and denominator by 5

= 40/60

So now we know the amounts

She gave 40 away so she has 20 left (60 - 40 = 20)

Now make 3/4 numerator and denominator by equal to 20

Multiply them by 5

15/20

She had 5 cookies left

8 A video game that usually costs $50 is on sale for $32.50

finlep [7]

The video game is on 35% discount.

Step-by-step explanation:

Cost of video game = $50

Price on sale = $32.50

Amount of discount = Original price - price on sale

$Amount\ on\ discount = 50-32.50\\Amount\ on\ discount= \$17.5$

Percentage = $\frac{Dicount\ Price}{Original\ Price}*100$

$Percentage=\frac{17.5}{50}*100\\Percentage=\frac{1750}{50}\\Percenatge=35\%$

The video game is on 35% discount.

olga2289 [7]

C) 5s - 0.2s is not equivalent. This would be paying for 5 snakes and subtracting 20% of the price of one snake, not 20% of the price of all 5 snakes.

There are 20 parrots at the animal sanctuary. Their population is increasing at a rate of 15% per year. There are also 24 snakes

worty [1.4K]

For the answer to the questions above,
A) Parrots are following a Geometric Progression of 15% increase.

20(1.15), 20(1.15)², 20(1.15)³,

Function = 20(1.15)^n Where n is at the end of year, n =1, 2, 3, ..

Snakes are increasing by 4.

28, 32, 36,....

Function = 24 + 4n    n = number of end year, n =1, 2, 3,...

<span>B) After 10 years:   </span>
Parrot = 20(1.15)¹⁰ = 80.91115471

Snakes = 24 + 4(10) = 64

<span>C) After what time they are the same: </span>
We use trial and error:

Test: n 20(1.15^n) (24 + 4n)
      1 23    28
      2 26.45 32
<span>      3 30.41    36   </span>
      4 34.98 40
      5 40.23 44
    6       46.26 48
      7 53.20 52
      8 61.18 56
      9 70.36 60

After year 7, the Parrots increases far more.
<span>At year 7 they are roughly the same.</span>
